Play for real money

Big Win 777 Slot by Play'n GO overview LogoBig Win 777 online slot is released by a casino software developing house known by the name of Play’N Go, which possesses over a decade of experience in this particular field, and has produced some of the finest online slot machines on the market. It was brought by Play’n GO to public on 24 October 2019.

The Big Win 777 slot game introduces a pretty much standard reel grid, designed according to the 5×3 pattern, which means that you get to land the symbols across five reels arranged in three horizontal rows. This reel grid contains fifteen paylines, across which you can create your potentially winning combination. The arrangement of these paylines can be found under the “Paytable” section of the slot demo.

The Big Win 777 slot mobile and desktop versions come with a volatility (variance) rate that goes between medium and high. This further implies that the included payouts are mostly bigger in size, but their occurrence frequency is smaller compared to low volatility slots and their payoffs. The return to player percentage rate is set to take the value of 96.5%, making the odds for winning quite high.

Design & Graphics of the Big Win 777 Slot Machine

As mentioned at the beginning of this Big Win 777 slot machine review, the game’s theme is based a fully retro-designed interface, which will give you the feeling of sitting behind an actual land-based slot machine from the 80’s. Of course, the game introduces top-notch graphics with kind of a blurry reel design, like they are constantly spinning in high speed.

The reel grid holds the largest part of the screen, which provides an excellent visibility of the symbols at any moment. The top of the screen is taken by a beautifully designed logo of the game. The bottom of the screen is reserved for all control buttons and infoboxes, such as your balance or the size of your bet. Through these buttons, you control each and every aspect of the game.

All in all, the Big Win 777 video slot by Play’N Go introduces a neatly designed, mobile compatible interface, which is simple to use and displayed in high-resolution graphics for the best possible online gaming experience, either you play for fun or with real cash.

Big Win 777 Slot Symbols, Bonuses

In order to play Big Win 777 for free in a proper way, it is recommended first to get familiar with the guide which included symbols and payout values their combinations tend to carry. The unusual thing about this online casino game is that, unlike the majority of online slots, it includes a smaller number of symbols, to be exact only six of them.

They can be divided into two major groups: bar symbols and 7 symbols The first group contains three tokens. These tokens come in the form of a single bar icon, a double bar icon, and a triple bar icon. The value of their payout combinations rises along with the increase in bar icon number, so you can win between the minimum of 0.15 credits, and the maximum of 1 credit during the base game, if you play a spin with the minimum wager (0.15 credits).

Symbols that contain number 7 come in two forms: as a red double 7 symbol and a gold triple 7 symbol. The first of them carries the maximum payoff worth 2.5 credits, while the golden one comes with the maximum payout worth 12 credits.

The symbols with the highest payout value is illustrated as a diamond and represents the wild symbol. If you manage to create a combination of five diamonds landed across a single paying line with a minimum bet, you will receive a prize worth 10 credits, which is, in fact, the base game jackpot payout!

You can also come across so-called Chance Scatter symbols, illustrated as a wheel of fortune. They carry no payouts, but they can grant you access to Big Win 777 slot features!

Symbol Payouts* 5 of them 4 of them 3 of them
Wild Symbol Wild 80 20 4
Golden Seven Symbol Golden Seven 20 8 2.40
Red Seven Symbol Red Seven 16 6 1.60
Violet Bar Symbol Violet Bar 8 4 1.20
Bronze Bar Symbol Bronze Bar 6.40 3.20 1.20
Cyan Bar Symbol Cyan Bar 4 2 1.20

*Winnings are multiplied by a total bet (current is 1.20)

Big Win 777 Slot Features

Big Win 777 Slot Machine Chance Wheel SymbolThere’s no a special slot strategy to apply to this mobile casino game to get the biggest win possible, but proceed with this game review to learn about the multiplier and other game features more.

  • Booster Spin. A Big Win 777 free play casino slot comes with several additional features. The first of them is known by the name of Booster Spin and can be activated randomly throughout the base game in any given moment. When triggered, this feature will make the process of getting three scatters easier, and getting them will grant you access to the remaining two features.
  • Chance Wheel. The first of these two features is called “Chance Wheel”, and you can access it by landing three or more Chance Scatters, which need to land on the first, the third, and the fifth reel. When this occurs, you get taken to a new screen displaying the wheel of fortune, which you then get to spin. This wheel carries several cash prizes, as well as an access to the game’s free spins bonus. Cash prizes come in several different sizes: 5x, 7x, 22x, 33x, 55x, 77x, and 777x the amount of your current bet! So if you want to achieve a big win, Big Win 777 will provide you the chance through this particular feature!
  • Free Spins. If you manage to start the free spins feature by spinning the wheel of fortune, you will be awarded 12 additional rounds. These rounds come with theoretically endless potential of re-triggering, while you are awarded one or two additional free spins if you land one or two scatters, and by catching three or more of them during the feature, you will receive five, ten or the maximum of twenty costless rounds! If you manage to land a diamond wild during the feature, it will become sticky, holding its position for two consecutive spins. And not only that, it will also duplicate itself and spread vertically, in order to cover the entire reel. Through free spins feature, you get the opportunity to win the Big Win jackpot prize, which takes the value of 5000x your total bet amount!

Controls & Interface

As mentioned in the introduction part of this Big Win 777 slot review, the game possesses a very neatly designed interface, with a centrally placed reel grid and all the control buttons below it. Here’s a short tutorial on how to use the game’s options.

Starting from right to left, you will first come across the yellow auto-play button. By clicking on it, you will open a new window displaying the number of automatic rounds, as well as some additional settings considering these rounds. You can select between the minimum of 10 and a maximum of 100 computer-controlled spins. You can also decide to end the auto-play mode on any win or if you win the bonus game (jackpot). You can also set the limit for the single win (even if you play for free) and choose to end the auto-play mode if your balance increases or decreases by a desired amount.

A green button located next to the auto-play button sets the reels in motion. Buttons labelled with + and – serve for determining the value of your total stake. You can do that by clicking on one of the displayed values, located between + and – buttons.

A yellow leftmost button with a letter “i” will take you to the paytable section. Between these buttons, you can see info boxes displaying your balance, as well as the value of your total bet.

In the bottom left corner, you can see several icons, through which you can access the game’s settings, or mute the sound, or activate the fast play mode (a lightning bolt icon).

How to Play Big Win 777 Slot Machine?

As in any other online casino slot that you play on mobile, the main goal is to create a combination of symbols which carries a certain payout (according to the paytable), and to land it across a single payline, starting from left to right.

After getting familiar with symbols and their combinations, you need to adjust the desired bet size, and click on the green “Spin” button, in order to spin the reels. If a winning combination occurs, you will be notified visually, and you will see the amount of the won payout.

If you manage to trigger some of the features, you will also be notified and taken to the feature automatically. Each of them comes with instructions, so you will find your way around pretty fast.

Big Win 777 Maximum Payout

This slot machine online comes with the maximum prize of 10 coins for the minimum bet of 0.15 coins, which you can win during the base game. However, if you manage to activate the free spins feature, you will get the opportunity to fight for the jackpot prize, which occupies the value of 5,000 times the amount of your total bet! Even if you are playing with the minimum stake, the jackpot takes the value of 750 coins!
